(US4844992-A)      Current connection device, for use in electrochemical battery cells, esp. fuel cells, comprises (a) metal plate means; (b) contact sheet means welded to both sides of (a) for providing pressure cushions to the cells; (c) elastomer frame means surrounding (a) and (b), completely sealing all edges on both sides of (a); and (d) metal strip means attached to (a) projecting through (c) to outside the battery cell for providing a current connection point.    Pref. (a) and (d) are comprised of copper. Pref. (b) are formed in a wave-like pattern.    ADVANTAGE -   The pole plate is integrated into the pressure cushion. The parts and structure are easy to fabricate.    (EP308761-B)      Assembly for current connection of a battery of electro- chemical cells, in particular fuel cells, with pressure pads in the form of metallic contact bodies respectively having two contact sheets, characterised in that in-between the two contact sheets (8,9) of each contact body there is circumferentially welded a metal plate (7), in that the metal plate (7) has a metallic shackle (11) projecting to the outside, and in that the metal plate (7) is provided on its edge with an elastomeric frame (10).    (DE3869030-G)      A module for the connection of a battery of electrochemical cells, specially of fuel cells with a pressure plate (1), made of plastic or plastic coated metal, a cell frame (2,3) and an elastomer frame (10) has a copper plate (7) with a copper lug (11) for the external current connection. Two electrodes (4,5) are connected to the plate (7) by corrugated contact sheets (8,9) which are welded to the latter. The spaces (12,13) are filled with a fluid to generate a pressure. The contact sheets are made e.g. of nickel with 1mm corrugations. The reactants (H2,O2) are supplied at a pressure of 2 bar, and the pressure medium (N2) at 3 bar.    ADVANTAGE -   This module permits an operation at a higher ambient pressure. The cells of a stack can be connected in parallel.
